2023 TOYOTA CROWN Engine Problems

I’ve noticed this a few months in from having new vehicle. Intermittent power Loss from a stop or merging into traffic from a stop. Very dangerous has happened in oncoming traffic. From a stopped position as you press on gas to go the vehicle like stutters or hiccups jerks like loss of power then proceeds to go. Happens daily. Taken to Visalia Toyota for check up and they state no error codes noted or cannot duplicate concern. Yet issue still occurs. Reported to Toyota number in manual and received a claim number.

On September 16, 2024 at approximately 13:20 my mother was driving her 2023 Toyota Crown in the parking lot of the post office and she was slowing down to park in a parking spot when all of a sudden the vehicle lunged, surges, jerks ,speeds forward all on the cars own with no physical driver commands . The car races forward all on its own while she is slowly pulling into a parking spot jumps the curb and crashes into a brick wall. The CVT ( Continuous Variable Transmission ) Is the problem and quite sure.

I have experienced several instances while driving of Hesitation/Non-Linear Acceleration from a stop. When light turns green, on occasion when I accelerate, the vehicle hesitates then lurches forward into traffic. Have also experienced this issue when waiting to make a turn - car hesitates then lurches forward. I have almost had an accident due to this issue. According to Toyota Crown internet forum, this is a common issue with the 2023 Crown Platinum and Toyota is not being helpful in dealing with this safety issue.

Transmission Vehicle did not respond to acceleration when I turned onto a feeder street causing us to almost be hit Problem did not reproduce when I took it to dealership to be corrected. Please note that the 23 Highlander with this exact engine had this exact problem and I've attached TSB-0087-23 that Toyota developed for that particular vehicle. AGAIN, THIS TSB IS NOT FOR MY 23 CROWN HOWEVER, MY CROWN IS EXPERIENCING THE SAME ISSUE.
